General Information on Galvanized Boat Trailer Axles

When it comes to buying trailer axles in Melbourne, Transtyle own rubber torsion axle provides a significant improvement to ride quality in comparison to the conventional spring axles because both sides of the axle operate independently from each another. The rubber elastomer springs also help to smooth out the ride by absorbing at lot of the bumps, hence it is also a quieter ride. Maintenance free and no lea spring to get rust.

Tyanstyle axles currently manufacture four series of the axle,

Series #1 - **Coming Soon**

Series #2 - With three size capacity 1250kg - 1500kg and 1700kg

Series #3 - With three size capacity 2000kg - 2200kg and 2500kg

Serise #4 - With two size capacity 2750kg and 3000kg

Transtyle rubber torsion axles are suitable for all types of trailers - boat trailers, car trailers, caravans, horse floats etc. They are available as Half Axles (2px unit) that will suit any chassis width, or a Full Beams Axle. The full beam axle is available as a Straigh5 axle or a V Shape axle.

The axle beams are Hot dip Galvanised and the torsion arm and inner metal shaft are finish with Dacromet plating for protection against corrosion.

Note: When using for tandem trailer it must allow for 20% degrease in axles capacity and 25% for Tri-axles trailer.

How Does Boat Trailer Axle Work

Four natural rubber cords within the main structure of the axle beam surround the steel torsion bar. The wheel/hub spindle is attached to a lever, called the torsion arm assembly. This assembly comprise of the torsion arm, torsion bar and spindle. When load is applied to the trailer, the torsion arm assembly pivots around the torsion bar, causing a rolling or compressive resistance in the rubber cords inside the axle beam.

The Transtyle rubber torsion axle offers a significant improvement to ride quality in comparison to the conventional spring axles because both sides of the axle operate independently from each another. The rubber elastomer springs also help to smooth out the ride by absorbing at lot of the bumps, hence it is also a quieter ride

Grease exchange system

All of our axles will come with Grease Exchange system, this system is the best to protect your wheel bearing from corrosion, wear and water entry. With the Transtyle Grease Exchange System, grease is pumped through the hub via the grease zerk located at the end of the grease cap. Grease is pushed through the bearings and out of the exit hole at the rear of the spindle. Ensure that the seal plug has been removed to allow the grease for flow through.

Old grease that was inside the hub is forced out and exits through the rear hold of the spindle. Continue to pump new grease through the system until you are able to see a steady flow of new grease coming from the exit at the rear of the spindle - this ensures that all of the old grease has been flushed out. Once lubrication is complete, replace the seal plug.

Capacity allowance

When using for tandem axle trailers, you must allow for a 20% decrease in axle capacity.

Example = two axles rated at 2500kg is suitable for a 4000kg ATM tandem trailer. When using for tri axle trailers, you must allow for a 25% decrease in axle capacity. Example = three axles rated at 2000kg is suitable for a 4500kg ATM tri axle trailer.

Mudguard clearance

When assembling the axles to the trailer, you must keep a minimum clearance of 100mm from the top of the tyre to the guard.
